Title: Thread take-up device
Inventor: SUGIOKA TAKAMI
IPC: B65H54/44
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To uniformly perform dyeing for thread and to improve the winding attitude of a winding package by providing a control means for changing a rotation command value or a power supply frequency supplied to a driving means. SOLUTION: The output of sensors 13, 15 is inputted to a control device 21. Induction motors 8, 9 drive bobbin holders 2, 3 at a designated rotating speed according to a commnand of the control device 21. A bobbin 5 is installed on the bobbin holder 3, and when thread taken up on the bobbin 4 reaches a designated amount, it is controlled to a desginated value by the sensor 15 according to the command of the control device 21. While the thread is wound, the rotating speed of a controller 1 is detected, and the induction motor 8 is driven by an inverter so as to reach a designated value. Thus, the control can be conducted following up the winding thickness of the thread by the control means, so that uniform dyeing can be performed from the winding start to the winding end to obtain a thread of high quality without uneven dyeying.

Filed: 1988-06-16
Abstract: PURPOSE:To provide the excellent deodorization performance to sulfur smells even when the compsn. is used in a dry state by incorporating (A) a quinone compd. and (B) a tin compd. therein. CONSTITUTION:The quinone compd. of the component (A) is quinones or hydroquinones. The quinones are not particularly limited if the quinones are the compds. having the structure in which the 2 hydrogen atoms bonded to the benzene ring of arom. hydrocarbon are substd. with oxygen 2 atoms and the hydroquinones may be the compds. consisting of one molecule each of the quinones and the compd. of the hydroquinone type obtd. by reducing the quinones. The tin compd. which is the component (B) may be any of the compds. contg. tin atoms. While the compounding ratios of the respective components can be properly selected according to the required performance of the desired compsn., the ratios are usually in a 1-500 pts.wt., more preferably 5-200 pts.wt. range per 100 pts.wt. of the component (A). The deodorization performance is poor in some cases when the ratio of the components except the component (A) is excessively low. Conversely, economic efficiency is poor if the ratio is too high.

IPC: H01P3/00
Filed: 1977-12-12
Abstract: PURPOSE: To produce an optical fiber cable, which has its core free from water pressure or thrust and which is excellent in flexibility, by arranging a corrugated metal pipe on a core assembly and by winding a single or twisted wire concentrically on the metal pipe.  
     CONSTITUTION: There is arranged on an assembly 2 of optical fiber cores a corrugated pipe 7 of metal such as iron, which is coated with polyethylene. This  coating is wound with a twisted wire 8, which is composed of iron wires 9, such  that it is turned concentrically clockwise at a twisting pitch about thirteen times of  the diameter of the corrugated pipe 7. The resultant winding is protected by an  outer protecting layer 6 of PP parn. Thus, even if a tension is applied to the twisted wire 8 so that a compression is exerted between the facing twisted wires, the  resultant stress can be prevented from being applied to the optical fiber assembly 2 by the action of the corrugated pipe 7 so that the increase in the transmission loss can be obviated.

CONSTITUTION:The continuous acoustic tube 5 whose sectional area increase gradually from the chamber 8a in the rear of the speaker 9, is provided. The ratio St/SD between the effective area SD of the diaphragm and the area St of the throat 6 is set from 0.6 to 1.0 while the ratio SM/St between the area St and the area SM of the opening 7 is set from 2 to 6. In front of the speaker, the chamber 8b is provided, where the port 10 is set and thus the phase inverting device is formed with the port 10 and the chamber 8b. By setting this constitution to resonate at such a frequency as the wavelength which is approximately equal to the length of the acoustic tube 5, a sound in the front radiated through the phase inverting device and a sound in the rear radiated through the acoustic tube 5 become in-phased with each other, hence a flat and highly efficient sound pressure frequency characteristic in the low frequency of sound pressure can be obtained. Also,by determining the area ratios above-mentioned, the sound pressure frequency characteristic can be made flat.
